4220 King Street presents a rare opportunity for a school, medical group, healthcare organization, or other institutional user to establish a campus in one of Northern Virginia’s most desirable and highly educated market corridors. The 17,172 SF building offers the scale and flexibility to support classrooms, clinical and specialty services, administrative functions, research, training, or multi-department operations - all within a highly accessible location with direct I-395 connectivity. Fully renovated in 2017–2018 and immediately operational, the property features substantial on-site parking, ADA-accessible elevators and restrooms, and the infrastructure needed to accommodate a broad range of institutional users without the significant capital requirements typically associated with acquiring and repositioning a facility. Surrounded by more than 40,000 residents within one mile, with a $113,500 median household income and 62% of residents holding a bachelor’s degree or higher, 4220 King Street is positioned within a strong, educated, and economically established community. Its 33-year history of continuous institutional occupancy by the American Geosciences Institute further demonstrates the property’s suitability for long-term organizational use. For schools and medical groups seeking to expand their footprint, consolidate operations, or transition from leasing to ownership, 4220 King Street offers a compelling combination of location, scale, substantial parking, accessibility, turnkey condition, operational control, and long-term growth potential.
